Checking hourly for aurora and zodiacal light. The transparency was poor, only down to about 4th magnitude. The Milky Way was not visible. When I checked last at 05:48 a.m., fog had set in so that Jupiter was the only object visible.According to The Weather Network, the temperature was steady at 10°C from 1 a.m. onward except for a drop to 8° at 4 a.m., which must have been what triggered the fog.Temperature = 10°C (mostly)

I checked the sky, looking for aurora (predicted) and zodiacal light, but could see neither. I later checked in Starry Night and found that the Sun was 18.2° below the horizon, so full astronomical twilight had not begun. I had the impression that the sky was lighter than full dark, so there may have been generalized airglow from aurora.Temperature = 8°C
